struts2中的include的实现

通过读取源代码,发现struts2是通过Xwork中的XmlConfigurationProvider来读取配置的.其中发现在xwork2.1版本中,是支持*号的通配读取.但在xwork2.0中是不支持这样的写法. 
所以在String2.1的版本中是可以使用<include file="resource/struts-config/*.xml"/>这样的配置.在Struts2.0中是不支持这样的配置 
xwork2.1 

Java代码  

1. if ("include".equals(nodeName)) {  
2.                             String includeFileName = child.getAttribute("file");  
3.                             if (includeFileName.indexOf('*') != -1) {  
4.                                 // handleWildCardIncludes(includeFileName, docs, child);  
5.                                 ClassPathFinder wildcardFinder = new ClassPathFinder();  
6.                                 wildcardFinder.setPattern(includeFileName);  
7.                                 Vector<String> wildcardMatches = wildcardFinder.findMatches();  
8.                                 for (String match : wildcardMatches) {  
9.                                     finalDocs.addAll(loadConfigurationFiles(match, child));  
10.                                 }  
11.                             } else {  
12.                                 finalDocs.addAll(loadConfigurationFiles(includeFileName, child));  
13.                             }  
14.                         }  

xwork2.0 

Java代码  

1. Element rootElement = doc.getDocumentElement();  
2.                 NodeList children = rootElement.getChildNodes();  
3.                 int childSize = children.getLength();  
4.   
5.                 for (int i = 0; i < childSize; i++) {  
6.                     Node childNode = children.item(i);  
7.   
8.                     if (childNode instanceof Element) {  
9.                         Element child = (Element) childNode;  
10.   
11.                         final String nodeName = child.getNodeName();  
12.   
13.                         if (nodeName.equals("include")) {  
14.                             String includeFileName = child.getAttribute("file");  
15.                             docs.addAll(loadConfigurationFiles(includeFileName, child));  
16.                         }  
17.                     }  
18.                 }  
19.                 docs.add(doc);  
20.                 loadedFileUrls.add(url.toString());
